I've decided to note down my sleeping patterns, in the hope that I can transit to a polyphasic sleeping pattern in the future :) I figured it would be easier for me since my work schedule is rather irregular. Haha. Another reason why I'm doing this is cos I realized that I tend to have a natural inclination towards doing my chores at night (like my body feels motivated to want to clear up my room before I sleep), and that's something that I totally am not motivated to do in the day at all.
Shall see how it goes :)
